Application filed February 19, 1923. Serial No. 619,889.

To all whom it may concern:

Be itknown that I, ALBERT T. NEWMAN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and usefullmprovements in Oil Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to oil burners and the primary object is to provide a simple burner which Wlll efiiciently vaporize hydrocarbon oils to convert them into gases to be mixed with air preparatory to ignition.

In order to provide an efficient burner, the oil should be thoroughly vaporized before it comes into contact with the air and the air should be combined therewith in such quantities as to promote combustion thereof to the best advantage.

. Hydrocarbon burner designers and manufacturers have long sought for a construc-. tion of burner wherein the accumulation of.

carbon will be reduced to .a minim-um because the accumulation of carbon in the burner passages obviously renders the same inefiicient and in most cases, entirely inoperative I believe I have provided a burner where the disadvantageous accumulation of deposition of the carbon will be practically nil but I have so constructed the burner that even should pure low grade oils be employed with a superabundance of carbon in them so as to cause some deposition of carbon, access can be readily had to the working passages so that the objectionable matter can be easily removed.

The novel construction of my invention will be apparent by reference to the following description in connection with the accompanying drawings, in which Fig. 1 is a vertical, longitudinal, sectional view through a burner constructed in accordance with my invention, and

Fig. 2 is a disassociated view of the several parts of the burner, the cap piece being shown in section.

Referring now to the drawings by numerals of reference:

- cone 7.

1 designates a base having downwardly projecting peripheral flan e 2 whereby the main body portion of the ase is supported above its support. The base is provided with a central'op'ening 3 surrounded by an upturned, curved flange 4 so that air can be directed through the opening and to permit the introduction of an oil supply pipe 5 therethrough. The oil supply pipe can be connected to any suitable source of supply, the port area'of the trolled by a valve 6.; The ischarge end of the pipe 5 is connected to a truncated The cone is inverted and it has a central concaved portion 8 surrounding the dis- (pipe to be concharge end of the pipe 5. A circumferential it immediately below a circumferential series of openings 13 in the wall of the cone. The inner face of the cone-shaped wall of the cone ,is provided with brackets 14, having shoulders 15 which engage the upper edge 16 of a ring 17 supported by a priming pan 18 having an overflow pipe 19. Therefore, the cone is su ported both by the pipe 5 and by the ring 1 the mainsupport, however, being the ring 17 on the riming pan.

The brackets 14 are of su cient widths to space the inner wall of the cone away from the ring 17 so as to provide a mixing chamber or space 20 between the ring and the cone, it being apparent by reference to the drawings that t e diameter of the cone is considerably greater than that of the 0; Therefore, the oils follow a tortuous passage to the overflow edge of the cone 7 j and then pass through the chamber or space 24 between the inner face of the cap and the outer face of the cone. The space 24 is formed by spacing the inner wall of the cap away from the outer wall of the cone as it fits over the shoulder 10. The cap is also provided with radial wings 25, extending from the outside wall so as to radiate the heat from the burner.

When the parts are assembled and oil is permitted to pass through the pipe 5, it will overflow into the cup 8, from there into the groove 9, over the side of the cone 7 through the openings 13 and into the priming pan. lit the flame is extinguished while the oil is flowing, the oil may escape through the overflow pipe 19'.

The oil in the priming pan can be i nited so that the burner will become hot. hen

.it does, the oilissuing from the pipe 5 will be generated into vapor or gas. It will flow over the top o-fthe truncated cone 7 through the space 24 and through the holes 13. The air passing through the opening 3 and through the ring 17 will pass over the upper edge 16 of the ring and combine with the gas in the mixing space or chamber 20. Then it will pass downwardly and upwardly, guided by the downwardly and upwardly curved peripheral flange of the priming pan so that the flame will be directed outwardly and upwardly in the. form of a ring; it not only will provide the necessary heat but it will also maintain the burner hot so that after.

- the burner has been primed, the burning V9.-

pors will maintain the burner at sullicient temperature to vaporize the oil.

lit is an important feature of my invention that the holes 13 are provided in the wall of the truncated cone so that they combine the maximum amount of air and provide a highly combustible mixture just before it reaches the point of combustion. Such a construction-will make a burner which will consume practically all of the hydrocarbon oils without residue and, therefore, there is little liability of accumulation of carbon. Tf there should be any accumulation, however, the cap can be readily removed and thecarbon disposed of.

aeaeea spaced therefrom, the lower edge'of the cap extending below' the opening and means for introducing oil through the top wall of the cone into the space between the cone and the cap, the cone being spaced from the ring which supports it.

2. An oil burner comprising a pan having a circumferential trough, an inverted cone having a recess in its top, the cone being smaller in diameter than the pan and supported above the edge of a central opening inthe pan, the cone having a depending wall with transverse openings therein, the wall of the cone being spaced from the pan, a pipe for feeding oil into the center of the recess in the top of the cone so that the oil may flow over the depending vertical wall of the cone and a cap covering the cone and having a depending wall extending to the bottom edge of the Wall of the cone.

3. An oil burner comprising a pan having a circumferential trough, a cone smaller in diameter than the pan and having a circumferential depending wall surrounding a central opening in the pan and spaced therefrom, the cone having transverse openings in. its vertical wall above the bottom edge thereof, a pipefor feeding oil over the top of the cone and a cap enclosing the top and vertical wall of the cone but in spaced relation to the cone.

4. An oil burner comprising a pair of inverted cones, one fitting over the other and spaced therefrom, both cones having a circumferential depending relatively thin wall, the inner cone having transverse openings between the top and bottom edge of the wall, brackets on the inner wall of the inner I cone and a ring upon the edge of which the brackets rest.

5. An oil burner comprising a pan having a central opening, an inverted cone supported by the pan but spaced therefrom, the cone having a relatively thin depending wall surrounding a central opening in the pan and provided with rows of transverse air openings, a grooved portion at the lower part of the depending wall, an outer cone spaced from the inner cone and having an inner wall conforming substantially to the wall of the inner cone, the inner cone having means for supporting the outer cone and means for supplying oil to the top of the inner cone.
